Manufacturer of Seawater Desalination Equipment

Seawater desalination equipment refers to the equipment specially used to desalinate seawater. Seawater desalination mainly uses two methods to desalinate seawater, namely distillation method and reverse osmosis method.

Seawater can not be used directly because of its very high salt content, mainly using two methods to desalinate seawater, namely distillation method and reverse osmosis method. Distillation method Distillation method is mainly used in super-large seawater desalination treatment and thermal energy rich places. Reverse osmosis membrane method has a wide application area and a high desalting rate, so it is widely used. Reverse osmosis membrane method is first to extract seawater, initial treatment, reduce seawater turbidity, prevent the growth of bacteria, algae and other microorganisms, and then pressurized with special high-pressure pumps, so that seawater into the reverse osmosis membrane, because of the high salt content of seawater, so the seawater reverse osmosis membrane must have a high desalination rate, corrosion resistance, high pressure resistance, anti-pollution and other characteristics, after the reverse osmosis membrane treatment of seawater, Its salt content is greatly reduced, with TDS content dropping from 36,000 mg/l to around 200 mg/l. The water quality after desalination is even better than tap water, so that it can be used by industry, commerce, residents and ships and warships. Reverse osmosis seawater has high salt content, high hardness, high corrosion to equipment, and the seasonal change of water temperature makes the reverse osmosis seawater desalination system more complicated than the conventional brackish water desalination system, and the project investment and energy consumption are much higher. Therefore, it is particularly important to reduce project investment and energy consumption through careful process design and reasonable equipment configuration, so as to reduce the cost of unit water and ensure the stable operation of the system.
